DHS disputes memo on purported railway computer breach

The Department of Homeland Security is disputing a government memo obtained by Nextgov.com that said a targeted attack on the computer network of a railway company in the Northwest disrupted train service in early December.

“Following more in-depth analysis, it appears that the potential cyber incident did not in fact target a transportation entity,” a senior DHS official told CNET today. “DHS worked with the affected entity, the FBI, and the Transportation Information Sharing and Analysis Center (ISAC) to resolve the issue and send alerts to notify the community of the anomalous activity as it was occurring.”
